Tmi! On my period

Aracely • Mommy of 1 waiting on BBy #2
Been in my period since Thursday 
​Now I see my bf once a week;(
​I've missed him :/
​I tend to want sex more on my menstrual cycle . 
​My bf and I had intercourse starting Friday till Sunday my period ends tomorrow . There's a slight chance a woman can get pregnant on her period right?
